20160028142 | Metal Plate Lens - Optical axis as central axis is defined as z-axis, and axes perpendicular to z-axis are defined as x- and y-axis. Metallic flat plates are formed parallel to x-z plane to overlap each other and be separated by a given distance. Multiple flat plates except the top flat plate and bottom flat plate are each provided with multiple through holes. Central flat plates are each provided with through holes of a first radius. Intermediate flat plates arranged between central flat plate and top flat plate and between central flat plate and bottom flat plate are each provided with through holes of a second radius smaller than first radius. Second radius of through holes formed in an intermediate flat plate arranged in a position farther from central flat plate is smaller than second size of through holes formed in an intermediate flat plate arranged in a position closer to central flat plate. | 01-28-2016 |
20140308811 | SEMICONDUCTOR INTEGRATED-CIRCUIT DEVICE AND METHOD OF PRODUCING THE SAME - A semiconductor integrated-circuit device using the copper wiring having increased electromigration resistance, low resistivity, and a line width of 70 nm or less, is provided. The present invention is characterized by the annealing treatment wherein a copper wiring having a line width of 70 nm or less is heated with a heating rate of 1K to 10K per second, and then the temperature is constantly maintained for a prescribed time duration. | 10-16-2014 |
20120329165 | BROMATE ION MEASUREMENT METHOD - A method for measuring bromate ion is provided that provides high-sensitivity measurement results more simply and more quickly than conventional bromate ion measurement methods. A fluorescent substance that is quenched by coexistence with bromate ions is added to a sample | 12-27-2012 |
20120148808 | TRANSPARENT FLUORINE-CONTAINING POLYMER - Disclosed is a fluorine-containing polymer obtained by polymerizing a 1,6-diene-type ether compound represented by formula [1] and, for example, a (meth)acrylic acid compound represented by formula [2]. The fluorine-containing polymer shows high transparency, has a high glass transition point, and is soluble in a solvent and therefore has moldability. In the case where a (meth)acrylic unit has a reactive substituent, by utilizing the crosslinking reaction thereof, a thin film having high solvent resistance can be produced. | 06-14-2012 |
20120146220 | SEMICONDUCTOR INTEGRATED-CIRCUIT DEVICE AND METHOD OF PRODUCING THE SAME - A semiconductor integrated-circuit device using the copper wiring having increased electromigration resistance, low resistivity, and a line width of 70 nm or less, is provided. The present invention is characterized by the annealing treatment wherein a copper wiring having a line width of 70 nm or less is heated with a heating rate of 1 K to 10 K per second, and then the temperature is constantly maintained for a prescribed time duration. | 06-14-2012 |
20120065320 | FLUORINE-CONTAINING 1,6-DIENE ETHER COMPOUND AND FLUORINE-CONTAINING POLYMER - A fluorine-containing polymer obtained using a 1,6-diene ether compound represented by formula [1] is a high-performance polymer exhibiting a low refractive index, high glass transition point, a high degree of transparency, and solubility in solvents. There are many potential uses, such as use as a coating material or bulk material. For example, said polymer could be effectively used in high-tech fields such as: optical materials such as low-reflection films and optical waveguide cladding; semiconductor materials such as pellicles and resists in semiconductor lithography; and protective film materials, insulating film materials, and water-repellent materials. | 03-15-2012 |
